Re: [PR] KAFKA-19688: add new KStreams.process() overlaod [kafka]

kpihlblad commented on PR #21003:
URL: https://github.com/apache/kafka/pull/21003#issuecomment-6132483139

   Looking into this and it seems as when  `__enable.process.processValue.fix__` is off, `KStream.process()` may break either silently or with an exception.
   
   - `selectKey().toTable().toStream().process().toTable()` throws `Found a null keyChangingChild node` at `build()`.
   - A key-changing `process()` in a sibling branch loses its repartition. No error.

   Is this still planned for 4.5.0? I can help with tests or a rebase. I'll file a bug but right now my Apache Jira account seem to be locked :-)
